找不到MongoDB数据目录/data/db [英] MongoDB Data directory /data/db not found

问题描述

当我尝试在终端中运行Mongod时，出现以下消息:

When I try to run Mongod in terminal I got this message :

2015-05-14T17:33:04.554+0700 I STORAGE  [initandlisten] exception in initAndListen: 29 Data directory /data/db not found., terminating
2015-05-14T17:33:04.554+0700 I CONTROL  [initandlisten] dbexit:  rc: 100

并运行mongo命令:

and running mongo command :

MongoDB shell version: 3.0.3
connecting to: test
2015-05-14T17:34:26.679+0700 W NETWORK  Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused

我尝试更改/var/lib/mongodb和/var/log/mongodb中的渗透，但仍然无法正常工作，我尝试再次卸载并安装mongodb，但仍然存在相同的问题. 有人可以帮忙吗?谢谢

推荐答案

MongoDB需要数据目录来存储数据. 默认路径为/data/db

MongoDB needs data directory to store data. Default path is /data/db

启动MongoDB引擎时，它将搜索此目录，该目录在您的情况下不存在.解决方案是创建此目录并为用户分配rwx权限.

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

如果要更改数据目录的路径，则应在启动mongod服务器之类的时候指定它，

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

这应该有助于您使用自定义路径和端口启动mongod服务器.

This should help you start your mongod server with custom path and port.
